Rich ore deposits, also known as LODES, are concentrations of valuable minerals or metals that are found within the Earth's crust. They are usually formed by hydrothermal activity and can be mined for their valuable resources. LODES are typically found in areas where there is a high concentration of certain elements, such as copper, gold, and silver. These deposits can be found in many different geological settings, including sedimentary, igneous, and metamorphic rocks.
